Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Open and closed-loop control systems

1.9K
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

    Area of Science:

    • Rehabilitation Engineering
    • Biomedical Engineering
    • Human-Computer Interaction

    Background:

    • Postural control rehabilitation can be enhanced using smart devices that provide biofeedback.
    • Biofeedback increases patient perception of their postural state through real-time sensory information.
    • Current methods allow rehabilitation exercises where patients use additional sensory inputs to control posture.

    Purpose of the Study:

    • To propose and evaluate a novel closed-loop control system for Center-Of-Pressure (CoP) using kinesthetic feedback.
    • To investigate the feasibility and robustness of this kinesthetic biofeedback system for postural rehabilitation.

    Main Methods:

    • A closed-loop control system was developed where a one Degree of Freedom (DoF) device's motion mirrored the patient's CoP position.
    • Patient's CoP data was obtained from a force plate, and kinesthetic feedback was provided via light touch on the device.
    • Experiments were conducted under ideal conditions and then in more realistic clinical settings.

    Main Results:

    • The feasibility of closed-loop CoP control using kinesthetic feedback was demonstrated under ideal conditions.
    • The system allowed for controllable displacement of the patient's CoP.
    • Initial experiments suggest the approach is robust enough for realistic rehabilitation scenarios.

    Conclusions:

    • Kinesthetic feedback offers a promising new modality for biofeedback in postural control rehabilitation.
    • This technology has the potential to improve patient engagement and outcomes in rehabilitation programs.
    • Further research is warranted to fully evaluate its clinical efficacy and application.
